SEALING FRUIT-JARS.

EPECIFIOATION forming part of Letters Patent No. 255,005, dated March14, 1882.

Application filed January 12, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH MURPHIN, a citizen of the United States,residing in Malaga, Gloucester county, New Jersey, have inventedcertainImprovementsin SealingFruit- Jars, of which the following is aspecification.

The object of my invention is to provide a means of sealing fruit-jarswithout the use of the ordinary devices for securing the cap, and thisobjectl attain in the manner which i will now proceed to describe,reference being had to the accompanying drawings, in which- Figure 1represents a sectional view of the upper end ot'thejar, the packingring,and the cap, the latter being removed from the jar; Fig. 2', a similarview, showing the first step in the operation of sealing the jar; andFig. 3, a view showing thejar sealed.

A is the upper portion of the jar; B, the rubber ring or gasket forsealing the same, and D the cap. Around the mouth of the jar are formeda contracted annular shoulder, a, a shoulder, d, below the same, and avertical or slightly undercut bearing-surface, b, between the two, andin the cap are formed internal annular shoulders, at and n, and anannular bearing-surface, t7, the radius of the latter be ing. greaterthan the radius of the annular bearingsurface b on the jar bya littleless than the thickness of the ring B.

In sealing thejar the ring B is first applied in the flatwise orhorizontal position to the shoulder a of the jar, beyond which thegreater portion of said ring projects, as shown in Fig. 1. The cap D isthen applied to the ring, the shoulder on of the cap resting upon theouter edge of the projecting portion of said ring, as shown in Fig. 2.Downward pressure is then applied to the cap, the result of this beingthat the ring B is caused to turn from the flatwise or horizontalposition to a vertical or edgewise position, in which it rests upon theshoulder 01, and is compressed and securely confined between the annularbearing-face b of the jar and the corresponding bearing-surface i ofthecap, as shownin Fig. 3,thusforming a hermetically-sealed joint. Theshoulder a of the cap bears upon the upper edge of the ring and servesto prevent in a great measure the access of the contents of the jar tosaid IlI] g.

In removing the cap it is necessary to tilt the same, as indicated bythe arrowin Fig. 3, it being diflicultin fact almost impossible-toremove the cap by a direct upward pull.

While I. prefer to use the shoulders in and n in the cap, theseshoulders are not absolutely necessary, and may in some cases bedispensed with, the lower edge of the cap taking the place of theshoulder m.

By my invention I am enabled to overcome both the inconvenience and theexpense of ordinary fastenings employing screw rings, clamps, or springsfor securing the cap.

I claim as my invention- 1. The combination of the flat annular ring orgasket 13, the jar A, having a contracted annular ring-supportingshoulder, a, and immediately below the same avertical bearing-surface,I), and the cap D, having an internal annular bearing-surface,i, of aradius greater than that of the surface I) by about the thickness of thering B, and-a shoulder adapted to bear near the outer edge only upon theringB when the latter is supported in its horizontal position, whereby,on depressing the cap, an abrupt quarter-turn is imparted to the ringand the latter is confined in a vertical position between thebearing-surface b on the jar and the bearing-surfaced in the cap, as setforth.

2. The combination of the flat annular ring or gasket B, the jar A,having a contracted aunular shoulder, a, a shoulder, d, below the same,and between them an annular vertical bearing-surface, b, equal in depthto the width of the ring, and the cap D, having an internal annularbearing-surface,i, exceeding the diameter of the surface b to the extentspecified, and a shoulder, m, adapted, when the ring B is supportedhorizontally, to bear upon said ring near the outer edge only, as setforth.

3. The combination of the'tlat annular ring or gasket B, thejar A,having a contracted annular shoulder, a, and an annular verticalbearing-surface, 1), below the same, and a cap, D, having a shoulder, m,an internal annular bearing-surface, i, and an internal shoulder,confined laterally between the bearings b and to n, the shoulder m beingadapted, when the i, as set forth.
